You may have to change your Google Account settings to be able to log in to the GWT Module. Do either of the following:
- Go to https://www.google.com/settings/security -> "Access for less secure apps" -> set to Enabled -> Log in to SM Data Grabber with your regular Google Account credentials
- Go to https://www.google.com/settings/security -> complete the "2-Step Verification" setup -> create an app-specific password at https://security.google.com/settings/security/apppasswords -> Log in to SM Data Grabber with your Google Account email and the app-specific password
We recommend the latter method, as it's more secure and recommended by Google.
